Using the Merida eBig Tour 400 EQ is a breeze. To start, just turn on the power switch. You can adjust the assistance level according to your riding needs and terrain. When riding in the city, a lower assistance level might be enough, while for off - road adventures, you can choose a higher level. When mounting the bike, use the low - step - through frame for easy access. When stopping in traffic, it provides stability. For safety, always wear a helmet and make sure the lights are working, especially when riding at night. As for maintenance, keep the battery charged regularly. Don't let it completely discharge. Check the tire pressure often to ensure a smooth ride. Also, clean the bike after muddy rides to prevent dirt from damaging the components. And don't forget to lubricate the chain every once in a while to keep it running smoothly.
